I have stayed for two weeks at Tip's place while working in Ramathibodi hospital, and it is very comfortable, clean and quiet. She was there to welcome me on arrival and responded easily on messages to provide help when necessary. Make sure you discover the rooftop terrace! It has a nice view and you can find the washing machine there. The BTS skytrain is near, which takes you to different areas very easily. If you like to walk around and buy local food, you should try to cross the railroad behind the building and find a very lively 'thai only' street behind. I do recommend staying here; although the area is mainly hospitals and schools and is not very touristic, it has the advantage that it is not crowded and busy. You can reach other areas easliy by the very convenient skytrain!
